Klampenhorg, Denmark, and Poul Ejnar Schou, Ordrupvej No. 94,Charlotteniund, Denmark Filed Dec. 21, 1962, Ser. No. 246,427 8 Claims.(Cl. 28-40) This invention relates to devices for warp leasing, and moreparticularly to a novel form of comb for effecting the separation ofwarp threads to permit the insertion of lease cords or rods. The leasingis done to maintain an orderly arrangement of the warp threads mainly tofacilitate the tying of new warp threads to the ends of runningout warpthreads. i

Various apparatuses are known wherein the comb consists of a row ofevenly spaced dents or needles each having a projecting hook on oneside, while the other side is plain. These combs are arranged to bemoved laterally in such a manner that previously inserted threads of anumber of warps will, when being raised by means of breaker rods, eitherbe engaged by the hooks or pass unhindered along the plain side of theneedles. In this way a lease will be formed to permit the insertion of alease rod, fixing the warps in a crossed relationship.

These known combs have the disadvantage of being selective by means ofthe lateral movement. This movement demands that the comb be exactly asbroad as the warp. If this is not so the threads will not run parallelfrom the beam through the comb and out again to the slasher, or anyother part of the weaving aggregate, with the result that the lateralmovement of the comb ceases to have any selective effect on threadswhich enter it at an angle. In such an apparatus there must be as manycombs as there are different warp sizes.

The present invention permits the employment of one comb for all warpsizes, because instead of moving the whole comb, it is the dents whichare moved, since these can be made to turn around their axis to changethe position of the projecting hooks in relation to the direction of thewarp threads. This novel comb will be more readily understood from thefollowing description taken in connection with the accompanyingschematic drawings, in which:

FIG. 1 is an end view of the improved comb showing it between two beams;

FIG. 2 is a top view of what is shown in FIG. 1, and showing the hookson the dents extending parallel with the warp;

FIG. 3 is a detail section on line IIIIII in FIG. 1;

FIG. 4 is a view similar to FIG. 2 showing the hooks extending acrossthe interstices between the dents;

FIG. 5 is a detail section on line V-V in FIG. 4;

FIG. 6 is a view similar to FIG. 1 showing a modified form of comb;

FIG. 7 is a top view of FIG. 6;

FIG. 8 is a detail section on line VHI-VIII in FIG. 6;

FIG. 9 is a side elevation of a lease;

FIG. 10 is a detail view of a portion of a comb showing a few of theteeth or dents in front elevation with downwardly inclined hooksextending crosswise of the warp; and

FIG. 11 is a view similar to FIG. 10 showing the dents with curvedhooks.

Referring now to the drawing, a warp 1 is shown drawn in full lines, anda warp 2 in broken lines. These warps 1 and 2 come from beams 3 and 4respectively, and pass 7 3,164,883 Patented Jan. 12, 1965 ICC sidewiseprojecting straight hooks 10. When dents 6 are turned so that thehooks'lil project parallel with the warp threads (as shown in FIGS. 2and 3) the warp 2 can be raised by means of breaker rod 8 to theposition 2' shown in FIGS. 1 and 6. When the dents 6 are turned abouttheir axis so that the hooks 10 project across the warp threads (FIGS.1, 4 and 5), the warp 1 can be raised by the breaker rod 9 to theposition 1' in FIGS. 1 and 6, and as warp 1 is raised it will be caughtby the hooks 10. In that manner a shed or opening is formed throughwhich a leasing cord or rod 12 can be inserted to fix the first half ofthe lease. Thereafter the dents 6 are turned so that their books againproject parallel with the warp threads, and then warps 1 and 2 arelowered into their initial positions. At that time warp 1 can be raisedby means of the breaker rod 9 without interference from the hooks 10.Thereafter the dents 6 are turned so that their hooks project across thewarp so that they will catch the threads of warp 2 when it is raised bymeans of breaker rod 8. In this manner a second opening is formedthrough which a leasing cord or rod 11 (shown in FIG. 9) can be insertedfixing the complete lease.

It is understood that hooks 10 are sufliciently embracing to ensure thatall threads are caught when this is desired. This is especiallyimportant if more than two warps are to be leased. It will be noted thatin FIGS. 5 and 8, the hooks 10 extend entirely across the intersticesbetween the adjoining dents and also crosswise of the threads. Hence nothread can escape being caught by a hook. The shape of hooks 13 may bevaried as shown in-FIGS. 5, 10 and 11. In FIG. 5 they are shown as beingstraight and'having a slight downward inclination. In FIG. 10 they areshown as being curved in a downward direction. In FIG. 11 they are shownas curving out, down and in again. The threads of warps 14 and 16 areraised above hooks 13 while threads of warps 15 and 17 are caught byhooks 13.

To facilitate turning of the dents 6 these may be furnished with cranks18 which are engaged by a ruler or connecting rod 19 to be movedsimultaneously. As shown in FIG. 1 the dents have their lower portionsextending through and rotatable in the comb body 5 with their projectinglower ends bent at right angles to form the crank arms 18, and the endsof the latter are bent upwardly at right angles and pivotally mounted inthe connecting rod or bar 19.

In case of an uneven number of warps it is of advantage to be able toturn every second needle or dent 6 simultaneously. This may be done byemploying two rulers connecting rods 20 and 21 as shown in FIGS. 6 and7.

It will be seenthat by mounting a row of upright dents for axial turningon a support such as the body of a comb, by providing the dents withendwise projecting hooks and by connecting either all of the dents orgroups of them for simultaneous axial turning, the connected dents maybe moved to either of two positions, in one of which the hooks aredisposed parallel with the warp and in the other position crosswise ofthe warp; and hence the device may be used for forming leases withoutany movement of the comb or other support and with very little move mentof the threads of the warp either vertically or horizontally. Thus theuse of the invention overcomes many of the disadvantages of priordevices used for forming leases.

We claim:

1. A warp leasing device comprising in combination a supporting body, arow of upright dents, means mount ing said dents on said body for axialturning movement and in spaced relation to provide dentspaces throughwhich the warp threads may extend, a sidewise project ing hook on eachof said dents, and dent operating 3 means including at least one movablemember operatively connecting at least some of said dents forsimultaneous turning movement from one position, in which the hooks ofthe moved dents extend in a direction parallel to the warps, to anotherposition in which such hooks extend in a direction crosswise of thewarps, whereby the use of the device permits the warps to be crossed toform two openings for the insertion of two lease members therein.
